REFRIGERATING AEFARATUS.

Application -led June 13, 1823.

' the provision of an improved construction allowing the use of cans or moulds having no bottom.

Another object of my invention is to provide a suitable means of separating` the water to be frozen from the freezing medium in a horizontal plane in such a manner that the water to be frozen will only freeze into ice at a certain distance bey low the freezing medium.

Another object! is to provide for the use of cans or moulds without any bottom so as to have at all times a full size opening of said mould for the precipitation of any impurity that may be in the water to be frozen.

Another object is the provision of an improved tank construction by the use of suitable heavy wooden timbers supporting the lower ends of bottomless cans or moulds and capable of supporting the coils, weight of freezing` medium, etc., thus -making unnecessary the use of cans having special constructed bottoms and I am able to pro- `vide in a single tank, o-ne compartment containing the brine and ammonia coils, and other compartments containing spaces for the ice to be frozen in; also a large heat-inN sulated non-freezing` zone for the precipitation of any impurities.

Another object is the elimination of the necessity of any provision being` made for the thawing of theice from the bottom of cans or moulds.

Referring to the drawing wherein l have illustrated a preferred embodiment of my invention,

Figure 1 represents a vertical longitudinal cross section of my invention,

Figure 2 is a vertical cross sectional view taken at right angles to the section of Figure 1 on the line 2-2 of Figure 1,

serial no. eli-5,086.

Figure 3 is a vertical cross sectional view on the line 3-3 of Figure 1,

Figure t is a cross section on the line M4 of Figure 1 and showing the timber supporting` construction,

Figure 5 is a cross section on the line 5-5 of Villigure 1.

The same reference characters refer to similar parts throughout the figures of the drawing. Y

10 designates the side of the tank, 11 the ends and 12 the bottom thereof.

1n my construction to be described, 1 have provided a brine space and a water space, the latter of which'is separated from the former by members having a low coeflicient of expansion. These members are preferably of a fibrous material and in the form shown, 1 have used wooden timbers. I have found that timbers 4L inches by 10 inches provide an excellent construction.

To the sides 10 are secured timbers 13 which preferably run the length of the tank. Parallel to the timbers 13 and spaced from each other and from the timbers 13 are timbers 14- similar .in size to the timbers 13. These timbers are preferably spaced, from adjacent timbers, a distance equal to one outside dimension of the cans to be used..

At the ends 11 and between the timbers 13 and 14 and between the timbers 14k, are other shorter timbers 15. Spaced at equal distances between the timbers 15 at opposite ends of the tank are timbers 16 similar' in construction to the timbers 15.

Between adjacent sides of the timbers are the cans 17, open at their bottoms as will be later described. to the timbers 13, 14, 15 and 16, respectively, by suitable bolts 1S. These bolts 1S pass through the timber and the adjacent can The cans 17 are secured walls and in the caso of the cans having walls adjacent the walls of the tank, lthe bolts 18 pass through the walls of the tank and furnisn a supporting` means for the cans and the frame work of timbers.

The timbers 13, 1e, 15 and 16 are suitably spaced above the bottom 12 of the tank. This space provides a reservoir and also permits the installation` of the pipe to be described.

During the construction of the tank, after the timbers and cans are in place, sealing material 19 in one or more layers, is run in between the outside walls of the cans and above the upper surfaces of the timbers. rIhis effectively seals thc chamber between the outer Walls of the cans and the reservoir 2O which as already described is connected to the interior of the cans.

A suitable air inlet 21, provides a supply of air for the air agitator pipes. 22 which extend beneath the center of Veach row of cans. Beneath the center, of each of the cans, is an opening 23, in the pipe 22,'forv providing agitation for the raw water. When raw Water is used for freezing purposes, this agitation caused by the rising of the bubbles fronithe openings 23, causes the impurities to be left in the unfrozen Water as the freezing takes place.

A suitable -Water inlet and outlet 24C, connected to the Water main, is provided as shown in .Figure l. *Above the sealing compound 1.9 and between the outer Walls of the adjacent cans Vis the brine space 25. 'Suspended' in this brine space 25 are the cooling pipes 26. 'A pipe 27Y leads to the ammonia supply and a connection 2T leads to the vacuum pipe.- r-i pipe 28 leads to a source of hot gas supply. rIlhe ammonia connection is used during the freezing operation and the het gas connection is used to warm the brine and the Walls of the cans when the freezingoperation is complete. This permits the ice to be easily withdrawn by means of the lifting rod 29 Which is frozen in Athe ice.

I have-provided partitions 30 to separate the brine space, except at Vthe ends, into two sections. In an enlarged portion 3l of the tank, I have provided a propelling inember 232 mounted on a shaft 33 Which is driven in any' suitable manner. lhen the propeller is put in motion, tbe brine is kept in circulationl as indicated by the arrows. thus keeping the Whole body of the brine at the same tcinj'ierature.

Freni the above description, it is clear that I haveprovided a simple, etlicient and cheap construction and one which will not be affected, by the temperature, to cause leaks; also eliminates the necessity of 'constructing cans or noulds with bottoms. Also providing` a large sediment chamber for the precipitation of any impurities, and, at the 1.521 ias same time creating a non-freezing zone, be;

yond which the ice will not freeze.

.'Vhile I have shown and described'in detail an embodiment of my invention, Y'I desire toV have it understood that I do not limit myself to the exact form shown and that modifications and changes'v may be inade Without departing from the spirit of my invention and Within the scope of the appended claims.

Having described my invention, what I claim is Y l. in ice making apparatus comprising a. tank, trie tank having a brine compartment, a raw Water compartment and ice compartments Within the brine compartments and so arranged that the brine sur-f rounds all of the sides of the ice coinpart-v a raiv Water Compartment and ice compartf ments, the ice compartments having substantially their Whole-bottoms open ^to the raw Water compartment and having-all of their sides surrounded -byfthe brine ofthe brine compartment, the raw Water compartment extending substantially throughout the area of the bottoni of the tank, andcheat insulating material adjacent the bottom vof the brine compartment and surrounding the ice compartments adjacent their bottoms. p

3. An ice making apparatus comprising a tank, the tank having a brine compartment, a raw Water compartment and ice compartments, the brine compartments surrounding the sides of the ice compartments and being separated fromrthe water compartments by Wooden timbers, bolts passingvthrough the timbers and theadjacent Walls of the ice compartments and outside Walls of the tank, and a sealing compound oiithe timbers .at tliebottom of the brine compartment.

In testimony whereof I aiiiX my signature.
